Yeah couldn't be happier for those who got the $1000 headers I got my headers, Intake and tune and still had money left over but for the money there great. Also yes I saw a difference but i recommend that you get it tuned AND DONT CUT THE O2 Sensors!! I did that and the car ran like SHIT! get o2 extensions from www.marylandspeed.com Its a good place and FAST shipping
